Probing SUSY at gravitational wave observatories
Physics Letters BUnder the assumption that the recent pulsar timing array evidence for a stochastic gravitational wave (GW) background at nanohertz frequencies is generated by metastable cosmic strings, we analyze the potential of present and future GW observatories for probing the change of particle degrees of freedom caused, e.g., by a supersymmetric (SUSY) extension

Coalescence of Kerr Black Holes—Binary Systems from GW150914 to GW170814
Entropy, 2019 We investigate the energy of the gravitational wave from a binary black hole merger by the coalescence of two Kerr black holes with an orbital angular momentum.

Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight
Experimental Physiology, EarlyView.Abstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...

Earth and Space Science, Volume 13, Issue 2, February 2026.Abstract The longest known Aletai meteorite belt presents a unique phenomenon in meteoroid dynamics. To investigate its formation mechanism, this study introduces a bilobate‐shaped meteoroid model, emphasizing aerodynamic interactions and structure evolution.

Prospects for determination of thermal history after inflation with future gravitational wave detectors [PDF]
, 2011 Thermal history of the Universe between inflation and big-bang nucleosynthesis has not yet been revealed observationally. It will be probed by the detection of primordial gravitational waves generated during inflation, which contain information on the ...

The NANOGrav 15 yr Data Set: Evidence for a Gravitational-wave Background
The Astrophysical Journal Letters, 2023 We report multiple lines of evidence for a stochastic signal that is correlated among 67 pulsars from the 15 yr pulsar timing data set collected by the North American Nanohertz Observatory for Gravitational Waves.

Differentiating Plumes and Local Torus Segments of Enceladus
Journal of Geophysical Research: Space Physics, Volume 131, Issue 2, February 2026.Abstract Enceladus's south polar plumes and their surrounding torus segments (local plasma regions formed by plume material diffusion) are key to understanding its magnetospheric interaction; however, clear observational criteria to distinguish them remain lacking.
